The major organs of excretion are the kidneys, a pair of bean-shaped organs located below the liver. The kidneys filter blood and regulate water balance in the body. The kidneys are the filtering devices of blood. The kidneys remove waste products from metabolism such as urea, uric acid, and creatinine by producing and secreting urine.
Urine may also contain sulfate and phenol waste and excess sodium, potassium, and chloride ions. The waste in your blood comes from the normal breakdown of active tissues and from the food you eat.
Your body uses food for energy and selfrepair. After the body has taken what it needs, from the food, the waste is sent to the blood. Humans have two kidneys and each kidney is supplied with blood from the renal artery. The kidneys remove from the blood the nitrogenous wastes such as urea, as well as salts and excess water, and excrete them in the form of urine.
How do kidneys clean the blood? Here's how kidneys perform their important work: Blood is cleaned by passing through millions of tiny blood filters. Waste material passes through the ureter and is stored in the bladder as urine. Newly cleaned blood returns to the bloodstream by way of veins. How do humans excrete? The main excretory system in humans is the urinary system.
The skin also acts as an organ of excretion by removing water and small amounts of urea and salts as sweat. They remove urea, toxins, medications, and excess ions and form urine. This lets pee go into the urethra and out of the body. Reviewed by: Larissa Hirsch, MD. Larger text size Large text size Regular text size.
What Are the Kidneys and Urinary Tract? What Are the Parts of the Urinary Tract? What Do the Kidneys Do? To help keep your kidneys and urinary tract healthy: Get plenty of exercise. Eat a nutritious diet. Stay hydrated. For girls: Wipe from front to back after pooping so germs don't get into the urethra. Avoid bubble baths, sitting in the tub after shampoo has been used, and scented soaps. These can irritate the urethra.
Wear cotton underwear. Promptly change out of wet bathing suits. Go for regular medical checkups. The primary function of the kidneys is the elimination of excess water and wastes from the bloodstream by the production of the liquid waste known as urine. The main structural and functional units of the kidneys are tiny structures called nephrons.
Nephrons filter materials out of the blood, return to the blood what is needed, and excrete the rest as urine. As shown in Figure By producing and excreting urine, the kidneys play vital roles in body-wide homeostasis. They maintain the correct volume of extracellular fluid, which is all the fluid in the body outside of cells, including the blood and lymph.
The kidneys also maintain the correct balance of salts and pH in extracellular fluid. In addition, the kidneys function as endocrine glands, secreting hormones into the blood that control other body processes. You can read much more about the kidneys in section Why can we regrow a liver but not a limb? Are sports drinks good for you?
Fit or Fiction. Why do we sweat? A set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate ATP.
A compound of nitrogen and hydrogen with the formula NH3. It is a common nitrogenous waste produced by the breakdown of amino acids in various cells in the body. Waste product of protein catabolism that is mainly filtered from blood in the kidneys and excreted in urine. A waste product of nucleic acid catabolism that is mainly filtered from blood by the kidneys and excreted in urine. The major organ of the integumentary system that covers and protects the body and helps maintain homeostasis, for example, by regulating body temperature.
An organ of digestion and excretion that secretes bile for lipid digestion and breaks down excess amino acids and toxins in the blood. An organ of the digestive system that removes water and salts from food waste and forms solid feces for elimination. Two paired organs of the respiratory system in which gas exchange takes place between the blood and the atmosphere. One of a pair of organs of the excretory and urinary systems that filters wastes and excess water out of blood and forms urine.
The body system responsible for the elimination of wastes produced by homeostasis. There are several parts of the body that are involved in this process, such as sweat glands, the liver, the lungs and the kidney system. From there, urine is expelled through the urethra and out of the body. Salty fluid secreted into ducts by sweat glands in the dermis that excretes wastes and helps cool the body; also called perspiration. Fluid produced by the liver and stored in the gall bladder that is secreted into the small intestine to help digest lipids and neutralize acid from the stomach.
A multi-branched polysaccharide of glucose that serves as a form of energy storage in animals, fungi, and bacteria. A brown pigment secreted into bile by the liver that is a byproduct of catabolism of dead red blood cells and is excreted in feces by the large intestine.
Solid waste that remains after food is digested and that is eliminated from the body through the anus. One of a cluster of tiny sacs at the ends of bronchioles in the lungs where pulmonary gas exchange takes place. A liquid waste product of the body that is formed by the kidneys and excreted by the other organs of the urinary system.
